Adding this D.C. sighting mentioning Kristen
According to this papzgeneyoung pics "Twihards Robert Pattinson has landed in DC for the #WHCD" Rob was alone he flew in from LA Kristen flew in from Vegas. Will post pics soon. Rob and Kristen were on separate flights I got pics of Rob I missed Kristen tryin 2 get @jhutch1992 Josh Hutcherson Clooney. I wont say 100% on Kristen 99.99% since I didnt see her but she was ticketed on that flight. I was looking for Clooney. Rob passed by so I got him by then Kristen had left the airport "

And from the VanCity pap that broke the DC NewsPunkd_Images (About Kristen) "Heard she flew out of Vegas 2 DC.. We'll see tomorrow if they show up at DC Event"
